Hookah bowl

ABSTRACT

A hookah bowl for a hookah is disclosed. The hookah bowl has a raised circular structure in center of the bowl, which has an opening at the apex. A concave area having one or more compartments is defined between inner walls of the upper bowl and the raised circular structure. As the opening is placed at the apex, the liquid in the additive laced tobacco does not leak into the stem or base of the hookah. An alternative embodiment discloses an option to hold multiple flavors of tobacco. The hookah bowl also has a hexagonal shaft extending substantially below the raised circular structure. A diametrically growing airway conduit is defined from the apex of the raised circular structure through the shaft and till distal end of the shaft for increasing the surface area the hot flavored smoke has to traverse before entering into the base of the hookah containing water.

BACKGROUND OF THE INVENTION

Hookahs are water pipes for smoking tobacco, whose popularity has spread worldwide. Since their creation, countless individuals have attempted to refine the basic design, which consists of at least four essential elements, a water container as the base, a stem, a bowl, and a hose. The water container holds water that filters smoke. Tobacco is placed in the bowl. The stem connects the bowl to the water container and contains a conduit for tobacco smoke to travel from the bowl into the water in the water container base. The hose connects to the stem and allows a user to draw the water-filtered smoke out of the water container.

Typically, the bowl containing additive laced tobacco is covered by a foil or other thermally conductive material, and heated charcoal is placed on top of the foil. The heat from the charcoal vaporizes the additive laced tobacco in the bowl as the user inhales through the hose. The charcoal is typically smaller than the bowl itself, requiring a smoker to periodically move the charcoal around the bowl in an attempt to achieve uniform heat distribution and vaporization of the additive laced in the tobacco. The heat distribution and the rate of combustion are affected by the air flow, thus making it desirable to optimize the air flow.

Hookah tobacco often contains additives such as honey, sugar, or glycerin, and other flavorings. It is desirable for the hookah tobacco to be subject to just enough heat to vaporize the additives. This results in smooth, thick, and flavorful smoke. Using a lower amount of heat to vaporize the tobacco also makes the tobacco last longer when smoking. Too much heat will end up burning the tobacco more quickly, resulting in harsh, irritating smoke. Therefore, heat management is an important part of the hookah smoking experience.

The hookah bowls traditionally had a flat or a concave bottom with holes disposed around the center of the bottom for the flavored smoke to pass through the stem when inhaled through the hose. A problem with such traditional design is that the additives drip down into the stem, reducing the amount of vaporizable material, and fouling the interior of the stem and the hookah water container.

SUMMARY OF THE INVENTION

To overcome various disadvantages in previous hookah bowl designs, a new hookah bowl that enhances smoking experience is disclosed.

The hookah bowl comprising a bowl, a raised circular spire in the center of the bowl, a concave area between the inner walls of the bowl and the spire, and a hexagonal shaft extending substantially below the bowl is disclosed. The spire in the center of the bowl has an opening at the apex. A concave area comprising of one or more compartments is defined between inner walls of the bowl and the spire. Further, an airway conduit is defined from the opening at the apex of the spire through the shaft and till the distal end of the shaft. The diameter of the airway conduit widens from the opening at the apex of the spire till the distal end of the shaft.

The concave area of the bowl holds the additive laced tobacco between the walls and raised circular spire. As the opening of the spire is at the apex of the spire, the liquid portion of the additive laced tobacco does not leak into the stem or the hookah water container. Further, the concave area may be divided into one or more compartments by the use of one or more side walls. Each of the one or more compartments could be loaded with different flavors of tobacco or the like. In this type of use, one or more heated charcoal pieces may be placed on a piece of foil covering the top of the bowl. The charcoal pieces may be moved around to heat a different flavor in each of the one or more compartments to enjoy a multi-flavored smoke, thereby improving the hookah smoking experience. The defined airway conduit having an increasing diameter from the apex of the spire and through the hexagonal shaft increases the surface area that the hot flavored smoke has to traverse, thereby decreasing the temperature of the smoke before reaching the water in the base.

The one or more compartments within the concave area may be substantially equally sized areas defined within the concave area, or unequally sized areas. When the one or more compartments are substantially equally sized, the additive laced tobacco or the like, possibly of different flavors, may be equally distributed within each of the compartments to have a smooth hookah smoking experience. Alternatively, when one or more of the compartments are unequally sized, the additive laced tobacco or the like, possibly of different flavors, may be unequally distributed in the compartments to vary the concentration and flavor of the additive laced tobacco to enjoy a varied hookah smoking experience. Alternatively, regardless of the size of the one or more compartments, the additive laced tobacco or the like, may be distributed in each of the compartments so that if the tobacco in one compartment is improperly heated and burns, the tobacco in the other compartments will not be burned and can still be smoked.

The raised circular spire may be replaced by a raised dome having one or more openings at the apex. The one or more openings at the apex of the dome is above the height of one or more side walls defining the one or more compartments. This arrangement enables uniform distribution of the heat from the heated charcoal for vaporizing the flavors in the additive laced tobacco or the like. Furthermore, the arrangements of the openings at the apex and its surrounding enable a uniform thick smoke for inhalation thereby resulting in an improved hookah smoking experience.

The diametrical growth in the airway conduit is either linear or any other arrangement that increases the surface area that the thick hot smoke has to traverse before entering the water in the water container of the hookah. In one embodiment, the hookah bowl is a molded bowl. Preferably, the hookah bowl is molded from silicone material because of heat resistance properties, increased grip for easier handling, and durability.
